New T4 Series Karting Championship Kicks Off This Weekend in Bulgaria

The 2026 season of the T4 Series karting championship in Bulgaria kicks off this weekend at the Kyustendil track. Drivers participating in the championship will have the opportunity for free practice sessions tomorrow, with official practice sessions starting on Saturday. Sunday will feature warm-ups, qualifying, and three races.

T4 Series Bulgaria Launches with Five Rounds This Season

In its debut season, the T4 Series Bulgaria will see drivers compete in two classes: “Bambino” and “Mini,” offering young participants their first steps in karting. T4 is a rapidly growing concept worldwide, leading to high demand for karts and creating a challenge for manufacturers to meet the needs of various championships.

“The T4 concept is gaining speed globally, which means the demand for karts is very high, and manufacturers can’t keep up with the needs of different championships,” explains Stanislav Kavarimov, co-founder of T4 Series Bulgaria. “That’s why we decided to have two full classes where young drivers can fully engage in the sport.”
